Question

A car is travelling at the average speed of 50 km/h.how much distance would it travel in 1hour 12minutes​

Answer 1

$\bf{{Given:}}$

Speed = 50 km/h

Time = 1 hour 12 minutes

$\bf{{To}}$$\bf{{Find:}}$

• Distance

Formula, which we will use:

Distance = Speed × Time

$\bf{{Solution:-}}$

Time = 1 hour 12 minutes

Let us change 12 minutes into hours.

$\to\bf\dfrac{12}{60}$(1 hour = 60 minutes)

$\to\bf\dfrac{1}{5}$

Time = 1 hour + $\bf\dfrac{1}{5}$ hour

= $\bf\dfrac{5+1}{5}$ hour

= $\bf\dfrac{6}{5}$ hour

Now, let us apply the Formula:

Distance = Speed × Time

$\bf{{50}}$×$\bf\dfrac{6}{5}$

$=\bf{{10}}$×$\bf{{6}}$

$=\bf{{60}}$km

$\therefore \bf{{Distance}}$$\sf{{travelled}}$$\sf{{by}}$$\sf{{the}}$$\sf{{car}}$$\sf{{=60}}$$\sf{{kilometers}}$

Speed, Distance & Time Formulas:

• Distance = Speed × Time

• Speed = $\bf\dfrac{Distance}{Time}$

• Time = $\bf\dfrac{Distance}{Speed}$
